Title: Driving device of photographing lens
Inventor: GUNJI KOUICHI
IPC: G03B3/00
Filed: 1984-06-13
Abstract: PURPOSE:To simplify the restoration means of a focusing device and to improve control accuracy by forming a specification means for stopping a cam member when the cam member of the focusing device to be circularly driven by a signal from a range finding circuit reaches the initial position after the end of photographing. CONSTITUTION:Since a pulse is supplied again from a control circuit to the 1st movable coil member after the end of photographing, a claw 117 advances and rotates the cam member 120 again in the clockwise direction. When the highest step of a step cam 122 reaches the position of a pin 132 of a lens frame 130, any one of projections 125a, 125b, 125c formed on the periphery of the step cam 122 contacts with a switch 126, so that pulse supply from the photographing lens 133 is interrupted and the rotation of the cam member 120 is stopped. Thus, the cam member controlling the photographing lens 133 to its focusing position can be restored to the initial position precisely without using a charging means, the restoration means can be simplified and the focusing control accuracy can be improved.

Title: Power mosfet and manufacture thereof
Inventor: KITAHIRA YASUO
IPC: H01L29/78
Filed: 1988-05-19
Abstract: PURPOSE:To reduce an ON resistance and to improve high speed switching characteristics by forming an N-type low resistance region on the surface of a substrate which becomes a drain, reducing the specific resistance of a surface region, and forming an opening in a gate electrode at the top of the low resistance region. CONSTITUTION:An N-type low resistance region 17 so selectively formed as to be brought into contact with a channel 16 at a boundary on the surface of a substrate 11 is so set to an impurity concentration as to reduce its specific resistance as to be lower than that of the N-type layer of the substrate 11. A doner impurity for forming the region 17 is not implanted into the surfaces of shallow P-type diffused regions 13, 14, and both are so controlled as to be brought into contact therewith only by lateral diffusion. An opening 20 of a desired shape is formed on a part which does not contribute to a MOS operation on the region 17 of a gate electrode 18 made of polycrystalline silicon disposed through an insulating film 19 on the channel 16. Thus, a resistance component presented on the passage of a drain current is reduced, and ON resistance at the time of operation can be reduced. An excess parasitic capacity may not be increased, and it does not disturb its acceleration.

Title: Soldering device
Inventor: ARISUE KAZUO
IPC: H05K3/34
Filed: 1985-06-07
Abstract: PURPOSE:To prevent sticking of solder to both end edges of jigs for conveyance by conveying parts to be soldered in the tight contact state by the jigs for conveyance which are held in place between rubber belts installed above and below. CONSTITUTION:The parts 1 to be soldered are attached to the jigs 2 for conveyance and are fed between the conveyor belts installed above and below in such a manner that the conveyance faces of the rubber belts 11 and 12 face each other. The parts pass over a solder tank 9 while the parts are sandwiched in an arrow B direction by driving wheels 13 and 14. The parts are then soldered by solder 10 blown up from the tank 9. The solder 10 blown up from the tank 9 sticks to the jigs 2 at the same instant when the parts 1 are soldered but both end edges of the jigs 2 are held in place between the belts 11 and 12 so as to tight contact therewith and therefore the solder 10 does not flow into the sandwiched parts. The parts where the solder corresponding to the sandwiching width of the belts 11, 12 at both end edges of the jigs 2 are not stuck are thus made to soldered parts 1 by the jigs 2.

Title: Tracking controller for magnetic recording/reproducing device
Inventor: SASAKI KOJI
IPC: G11B5/588
Filed: 1990-05-14
Abstract: PURPOSE:To attain the stable tracking control by setting a prescribed range to a discriminating circuit and holding the phase difference as it is between a reproduction control signal and a phase reference signal of a capstan when the integral value of the DC voltage component applied to an electricity-machine transducer is set in the prescribed range of the deciding circuit.

Title: Waveform shaping circuit
Inventor: KOUNO MITSUKUMO
IPC: H03K5/08
Filed: 1985-06-07
Abstract: PURPOSE:To quicken the response speed by inserting a diode element to the 3rd current path tying among the 2nd switching element, a current mirror circuit and a reference potential point so as to set accurately an output current value. CONSTITUTION:A diode is provided between collectors of a transistor (Tr) Q2 and Tr Q7 in the forward polarity. If an input voltage Vin is decreased to be lower than a reference voltage Vr, a Tr Q1 is turned on and the Tr Q2 is turned off, and the Tr Q7 is saturated to be turned on. Thus, the leakage current generated in the Tr Q2 and the electric charge stored in the base of a Tr Q6 are fiven to earth GND via the diode D and the Tr Q7. Thus, the output current Iout reaches immediately the state of iL=0 from a value iH. When the voltage Vin is higher than the voltage Vr, the Tr Q1 is turned off and the Tr Q2 is turned on. The changeover from the ON to OFF state of the Tr Q7 is delayed by the electric charge storage effect of the Tr Q7. In this case, the Tr Q6 is made active by the drop voltage of the diode D.

Title: Regenerating method of cation exchange resin in condensate desalination apparatus
Inventor: NAGATA YUSUKE
IPC: B01J49/00
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To regenerate cation exchange resin whose function is lowered in a relatively short time by including a scrubbing process by air or an inert gas as to make the integrated ventilation quantity be a specified value at the time of regenerating the ion exchange resin by passing a chemical reagent through. SOLUTION: In the case of regenerating cation exchange resin used in a condensate desalination apparatus in a thermal power plant, the ion exchange resin in a desalination tower which reaches the water flow final point is transported to a regeneration tower 20. Then, back wash water is passed through from a lower part pipe 2 to pass an acidic regenerating agent through the cation exchange resin existing in a lower layer part of the tower 20 and the agent is discharged by a pipe 5 through a collector in a middle part of the tower 20 to regenerate the cation exchange resin. After that, only cation exchange resin is transported to a storage tank 30 and scrubbing is carried out and at that time, the integrated ventilation quantity for scrubbing is controlled to be 70[Nm<3> /m<2> ] or higher.  The water in the tank containing organic eluted substances is exchanged with clean water by back washing or descending flow washing.
